Letters Patent No. 101,720, dated April 12, 1870.

IMPROVEMENT IN SULKY CULTIVATORS.

Thev sc heule referred to in these Letters Patent and making part of the same.

-on the line z.

The improvements I- claim to have'made consist principally in the manner in which I obtain thehcrizontal -motion of the two front dodging shovel-beams a, and in the simplicity of the construction of the,

main frame C. l

rlhe main frame consists of but three pieces, shown in iig l1, resting on and fastened to the iron axle el, to whicl axle the two front dodging shovel-posts a are attached by means of boxes e, iig. 2, so they will slide horizontally for the purpose of plowing crooked r'ows.

The horizontal motion -is imparted to said shovelbeams by means of thc operator placing his feet on either .end-of the the seat h.

Attached to either end of said cross-bar is a chain or rope, n., which, after passing through the stapleor pulley o, on the inside of the main frame O, connects with the shovel-posts a, as shown in iig. 1.

It will be readily seen that by working said crossbar on its pivotat the center, the slmvel-posts a will be moved to any place desired.

1n most machines of this character these two front shovel-posts are attached to the frame in advance of the axle, in which case they cause a heavy weighton the horses necks when in operation.

It will be readily seen that this is in a measure avoided by having them attached to the axle as shown, and the other sliovehposts all being in the rear of the axle, there can be little or no weight on the horses necks, especially when the seat h maybe adjusted forpivoted cross-bar t', as he ridcsjj-n ward or backward, as shown in fig. 1, so the weight of the operator will assist in balancing the machine.

In case the operator should desire to walk in the rear of the machine while at work, he can operate the shovel-posts a by means of the lever m, as shown in the. figures.'

The simplicity of the frame consists in the employl ment of but three main pieces c, and they are strengthcned so there will be no wrenching of the parts by means of the tongue fr, which attaches to the crossbar of the frame C, and to the axle d at its center by means of the post s, fig. 2, and extends far enough back to receive the seat h, as shown.

In order to regulate the depth of the plows in the ground, 'or to litt t-hem Vout entirely, I use the roller 71 mounted on the front end oi' the frame C, as shown, 1o which I attach the shovel-beams by means of chains c, which wind upon said roller by means of operating the lever .t backward or forward, and may be retained at any desired point'I by means of the notched segment u, as showin The whole machine is mount-ed on wheels, as shown, in the ordinary way.

Having thus described my invention,

What I claim as'new, and desire to secure by Letters Patent, is as follows:

1. lhe combination ofthe shovel-posts a, axle d, boxes e, chains 1t, pivoted cross-bar fi, and lever m, arranged, operating, and constructed as and for the purposes set forth.

2. The main frame G, in combination with the roller b, segment u, lever z, and chains c, arranged, 'operatiug, and constructed as and for the purposes set forth. i
